Veterinary instrument



Novl 2, 1937. A. H. JUNGE VETERINAR? INSTRUMENT Filed April 2, 1955 gmwmAri/Mr E Jiuge Gum/wan Patented Nov. 2, 1937 UNITED 1 Claim.

My invention relates to a veterinary instrument of the obstetrical typefor use in connection with cows and mares.

It is well known that a calf or fetus lies on its breast within theuterus, but due to the fact that it rolls on its back, or nearly so, ittakes the uterus along with it resulting in the twisting or torsioningof the uterus neck whereby the latter is closed to parturition.

It is the aim of my invention to overcome the objection referred to, andto this end, my invention resides in the providing, in a manner ashereinafter set forth, means for removing the twist or torsion in theneck of the uterus, as well as positioning the calf or fetus in a normalanterior pres.- entation or a posterior presentation.

Further objects of my invention are to provide, in a manner ashereinafter set forth, an instrument for the purpose set forth which issimple in its construction and arrangement, strong, durable, compact,thoroughly efficient in its use and comparatively inexpensive tomanufacture.

To the above ends essentially and to others which may hereinafterappear, my invention consists of such parts and such combination ofparts which fall within the scope of the invention as claimed.

In the drawing:

Figure 1 is a view illustrating the uterus of a cow having a calfarranged therein and further showing the application of the instrument,in accordance with my invention, for removing the twist or torsion inthe neck of the uterus and changing the position of the calf, and

Figure 2 is a perspective view of the veterinary instrument, inaccordance with my invention.

With reference to the drawing. 3, 4, and 5 indicate respectively a cow,its uterus and the neck of the latter. Within the uterus is shown a calf6 lying upon its back.

The instrument, in accordance with my invention, includes an elongatedstem 1 of circular cross section and of the desired diameter and length.The inner end of stem I merges into a closed loop or eye 8. Theouter endof stem '1 merges into a combined diverging and converging head 9merging into a semi-circular flat protuberance l0 intersected centrallyby the longitudinal median of the head. The latter diverges for thegreater portion of its length from stem '5 and then converges into theinner ends of the sides of the protuberance iii. The edges and facesrespectively of the head and protuberance are rounded and flat. Thefaces of the protuberance form flush continuations of the faces of thehead. The thickness of the head and protuberance is less than thediameter of the stem. The head, in proximity to its point of mergencewith the protuberance, is provided with an opening i i. The head 9 issubstantially of pear-shaped contour. The side edges of said head are ofcompound curvature. Carried by the head is a flexible element of thedesired length and which, by way of example, is in the form of a chaini3 which extends through opening II and is designed for forming anadjustable loop lid. The chain i3 is provided at one end with a splitretaining ring it of greater diameter than opening H and at its otherend with a rectangular endless link l5 having its width greater than thediameter of chain it.

When using the instrument, the chain i3 is passed through link l5 toform a loop lt The chain is then passed through opening i i andconnected to head 9 by ring M. The veterinarian then places the loop lain the uterus and slips it over a leg of the calf or fetus. Theveterinarian guides the instrument in the uterus, while an assistantrevolves the stem through the medium of a bar l6 extended through loopor eye 8 until the twist or torsion is removed from the neck 5 of theuterus t. The non-looped portion of chain I3 winds on rod 1 until loopEt is tight around the leg of the calf or fetus. The stem l is turnedeither clockwise or anti-clockwise, depending upon what direction thetwist in neck 5 extends. During the removal of the neck twist ortorsion, the calf or fetus is shifted from the position shown in Figure1 to lie in a normal anterior presentation. It is to be understood thatthe instrument may be employed in the same manner as on a posteriorpresentation. It is also to be understood that the instrument may beconnected to the nose, head or neck of the calf or fetus.

What I claim is:

In a veterinary instrument; a straight, elongated revoluble metallicstem having an integral endless part at its rear end forming a loop forthe passage of a revolving means for the stem and an integral fiatoppositely flared head part at its other end formed with curved sideedges, said head part being provided intermediate its ends with anopening, a metalic chain extending through said opening, a removablemetallic ring attached to one end of said chain and coacting with thehead part for connecting the head part and chain together, said chainadapted to have a portion thereof wind on said stem, on the revolving ofthe latter and an enlarged metallic link carried by the other end ofsaid chain for the passage of a stretch of the latter and coacting withsaid stretch to form an adjustable metallic loop adjacent that portionof the chain wound on said stem.
